In 1932, Karl Jansky at Bell Labs revealed that stars and other objects in space radiated radio waves. Credit: NRAO/AUI. Radio waves have the longest wavelengths in the electromagnetic spectrum. They range from the length of a football to larger than our planet.Heinrich Hertz proved the existence of radio waves in the late 1880s. He used a spark gap attached to an induction coil and a separate spark gap on a receiving antenna.n 1932, Karl Jansky at Bell Labs revealed that stars and other objects in space radiated radio waves.

Transverse waves are wave in which the vibrations of the particles or medium in which the wave travels are at right angles to the direction in which the wave travels. Water waves are an example of transverse waves. These can be observed in a ripple tank. The animation below shows transverse waves created in a ripple tank. From the above animation it can be seen that the rubber duck only moves up and down whilst the energy of the wave moves along the tank.
